"Q: What’s keeping us from modeling a human brain, neuron by neuron, on a computer?
Thank you for making me so wonderfully complex!
Your workmanship is marvelous—how well I know it.
Psalm 139:14 NLT
A: There are a lot of projects that are trying to do just this, but you have to realize, the brain is by far the most complex system scientists have ever tried to understand. A human brain is composed of roughly 100 billion neurons, and those form a very intricate but also incredibly dynamic network.One issue is that modeling these neurons requires very computationally expensive
math. Every single neuron has to be defined by a number of different variables, and each variable requires a set of differential equations to run. And don’t forget, we’re talking about having to individually compute all those equations for all these variables
for 100 billion neurons all at the same time.
Right now, with our best computer models, we can successfully model up to (roughly) 10,000 neurons, and that takes a very long time. But when you try to add more and more neurons, the system just breaks down and no longer acts anything like the neurons in the brain." PopularMechanics
